Abstract :
A fast Fourier transform (FFT) Radix-2 based approach using a gamma-ray spectrometer for the identification of radioactive mineral is presented. The proposed method reduces the complexity of diagnosis associated with the spectrometer by transferring time-domain analysis to frequency-domain analysis. The operation of PDA/DSP is discussed pragmatically.
